In this study, an experimental investigation had conducted for six high strength laced reinforced concrete one-way slabs to discover the behavior of laced structural members after being exposed to fire flame (high temperature). Self-compacted concrete (SCC) had used to achieve easy casting and high strength concrete. All the adopted specimens were identical in their compressive strength of ( , geometric layout 2000 750 150 mm and reinforcement specifics except those of lacing steel content, three ratios of laced steel reinforcement of (0.0021, 0.0040 and 0.0060) were adopted. Three specimens were fired with a steady state temperature of  for two hours duration and then after the specimens were cooled suddenly by spraying water. The simply supported slabs were tested for flexure behavior with two line loads applied in the middle third of the slab (four-point bending test). The average residual percentage of cubic compression strength and splitting tensile strength were 57.5% and 50% respectively. The outcomes indicated that the residual bending strength of the burned slabs with laced ratios (0.0021, 0.004, 0.006) were (72.56, 70.54 and 70.82%) respectively. However; an increase in the deflection was gained to be (11.34, 14.67 and 17.22%) respectively with respect to non-burned specimens.

An increase in the cost of conventional aggregate and the resulting environmental ecological imbalance has propelled research in the use of organic and industrial wastes as alternatives. The use of palm kernel shell concrete (PKSC) for structural applications such as beams is yet to be explored, mainly as a result of fewer research in the flexural strength of PKSC. This study investigates the flexural strength of palm kernel shell concrete (PKSC) for structural applications such as beams. Standard 150 x 150 x 150mm cube size and 100 x 100 x 500mm prisms of PKSC samples were casted at 1:1:2 mix ratio at water cement ratio of 0.5, and tested at age of 7, 14, 21 and 28 days according to BS EN 12390 – 3 (2002) and BS EN 12390 - 5 (2000). Method of batch by volume was adopted. At 28 days, the results show that the PKSC beam can support a load of 3981N with a deflection and flexural strength of 0.947mm and 2.883N/mm2 respectively. Also, the theoretical values of flexural strength and deflection compares well with the experimental values. A power equation in the form y = axn relating flexural strength with compressive strength produced a R2 value of 0.94 and relative predictive error of 0.028, the latter compares well with ACI 363 (1992) minimum value of 0.026 for power equations.
